ELECTRIC-CONDUCTOR SUPPORT.

SPECIFICATION forming part of Letters Patent No. 445,594, dated February3, 1891.

Application tiled July 80,1890. Serial No. 360,366. (No model.)

To all whom t may concern:

Be it known that we, CHARLES FOSTER and WILLIAM H. BEvIs, citizens ofthe United States, residing at Cincinnati, in the county of Hamilton andState of Ohio, have invented certain new and useful Improvements inElectric-Conductor Supports; and we do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to malte and usethe same.

Our invention relates to improvements in electric-conductor supports.

The object of our invention is to devise a simple, inexpensive, anddurable support for electric conductors, especially overheadelectric-railway conductors.

The invention consists, primarily, in a suitable clamp, which directlyembraces and holds the conductor, and in the combination of that devicewith other connecting' and supporting parts.

Figure l is a mid-sectional view along the line .n x, Fig'. 2. Fig. 2 isan exterior view at right angles from the view of Fig. l. Fig.` 3 showsa inodiiieation of the clamp proper.

The same numbers refer to the same parts in diilerent figures.

l is the stem of the clamp; 8, the body; 2, a medial slot open along thelower edge I of the clamp-body; 3, a hole through the clampbody adjacentthe lower edge and parallel with that edge, and l0 is a threaded hole inthe stein l by which the clamp is attached to supporting means. Theother parts of the device are such as are now in common use. All of theparts shown are connected to and supported by the hanger 1S, which has acentral boss 20 and a roof-shaped body 1S, having holes 19 in which thesupports for insulating-spools are secured, the hanger being supportedby wires fastened to these spools and extending in line with thehanger-body.

An insulating-bushingl IG is placed within the boss 20, and thescrew-bolt ll l2 13 is secured in the bushing. A head or shoulder l2 isformed on the upper end and a screwthread on the lower en d. Theprojecting' end 13 may be secured to the cap li in any suitable manner.Since the cap 14. is made of molded rubber, the end 13 is preferablycast to the cap.

Another cap 17 is placed between the lower end'of the hanger-boss 2O andthe boss 5 of the conductor-clamp. The parts l5, i6, and 17, being madeof insulating material, effectually insulate the parts l ll l2 from thesupporting-hanger 1S. 9 is a piece of a conductor clamped and held bythe device 8.

In Figs. l and 2 the clamp S is made integral and with a slot 2 ofsufiicient .width to allow of any desired variation of adjustment inclamping a conductor.

The hole 3 is made as close as possible to the edge 4, so that theclamping device will not interfere with an easy passage of the trolley.'Ilhe clamp is adjusted and tightened by means of one or more screws 0.

Fig. 3 shows a modification of a clamp made in two parts, the part 7forming one side of the clamp below the upper edge of the slot 2, andbeing held in place by the same screws G, which are used to adjust andclamp the conductor.

IVe claiml. The electric-conductor support consisting of the combinationof a conductor-clamp having a supporting projecting part, a hangerhaving a central vertically-perforated body part and integralside-sujiporting parts having eyes at their ends, a roof shape, andparallel sides forming a cover for supportingconnections, a bolt securedin the perforation of the hanger-body and connecting the parts together,and suitable insulating material interposed between the connecting-boltand the other parts, substantially as set forth.

2. The electric-conductor support consisting of the combination of aconductor-clamp having a supporting projecting part, a hanger having' acentral vertically-perforated body part and integral side-supportingparts having eyes at their ends, a roof shape, and parallel sidesforming a cover for supportingconnections, a bolt having a head at topand screwed into the clamp projection at bottoni as means for connectingthe parts of the device, and insulating material interposed between thebolt-body and its head and the contiguous parts connected together bythe bolt, substantially as set forth.

3. The electric-conductor support consisting of the combination of aconductor-clamp having a supporting projecting part, a hanger having acentral vertically-perforated body IOO part and integral side-supportingparts having eyes at their ends, a roof shape, and parallel sidesforming a cover for supportingeonnections, a bolt having a head at topand screwed into the clamp projection at bottom and held in the verticalperforation of the hanger as means of connecting the parts of thedevice, and an insulating spool or sleeve interposed between the boltand the hangerbody, the bolt-head engaging the end of the sleeve andclamping it endwise, substantially as set forth.

4. The electriccondnctor support consisting of the combination of a condnoter-clamp having a supporting-stem with a fiat endbearing surface andan end-threaded recess, a hanger having a central verticallyperforatedbody part 'and integral side-supportin g parts having eyes at their end,a roof shape, and parallel sides forming a cover forsupporting-connections, a bolt having a head at top andl screwed intotherecess of the clampstem 'at bottom, and an insulating-sleeveinterposed between the bolt and the hangerbody, the sleeve being`clampedbetween the bolt-head and the end of the clamp-stem, substantially asset forth,

5,"The electric-conductor support consisting of the combination of aconductor-clamp having a supporting-stem with a at endbearing surfaceand ank end-threaded recess, a hanger having a centrallverti'callyperforated body part andintegral side-supporting parts havingeyes at their ends, a root1 shape, and parallel sides, forming a coverfor supporting-connections, a bolt having a head at top and screwed intothe recess of the clampsteln at bottom, a bell-shaped cap of insulatving material interposed'between the hanger body and the end of theclamp-stem, and an insulating-sleeve interposed between the boltbody andthe hangerbody, the bolt passing through the said cap and clamping itagainst the end of the clamp-stem, substantially as set forth.

6. The electric-conductor support consisting of the combination of aconductor-clamp having a su pporting-stem with a ilat endhearing surfaceand an end-threaded recess, a hanger having a centralvertically-perforated body p'art and integral side-supporting partshaving eyes at their ends,a roof shape, and parallel sides forming acover for supporting-connections, a bolt having a head at top andscrewed into the recess of the clampstem at bottom, an insulating-sleeveinterposed between the bolt and the hanger-body, anda topweather-protecting cap secured to a projection of the bolt-head, all ofthe parts being secured together by the central bolt, substantially asset forth.

7. The electric-conductor support consisting of the combination of aconductor-clamp having a supporting-stem with a Hat endbearing surfaceand an end-threaded recess, a hanger having a centralvertically-perforated body part and integral side-supporting partshaving eyes attheir ends, a roof shape, and parallel sides forming acoverfor supporting-connections, a bolt having a Ahead 'at top andscrewed into the recess, of the clampstem at bottom, aninsulating-sleeve having a flanged end collar at topa'ndinterposedbetween the bolt-body'and'the hanger-body, the bolt clamping the partstogether and the said collar insulating the bolt-head from the upper endof the hangerfhody, substantially as set forth.'

In testimony whereof we now aihx our signaturesin presence of tw'owitnesses.

CHARLES FOSTER, VILLIAM H. BEVIS.
